2017 MacBook Pro 1708 - one of the USB-C ports is unreliable
I have a 13” 2-port Macbook pro (non-touchbar) where one of the USB-C ports is unreliable. Sometimes I can connect an external screen to it, sometimes a simple flash drive works. Other times it doesn’t. Sometimes it helps if I rotate the USB-cable. Today I actually successfully made it charge through that port - I had previously given up on that…
The other port seems to be working just fine, however I do recall once or twice where I had to take the plug out and try it again.
I know that this version has the ports soldered to the motherboard so I’m not going for that repair myself. But does the problem come from the ports themselves or could it be the chip ‘behind’ them? How can I determine this?
Is dit een goede vraag?
